Backendless

Backendless is a visual app development and backend-as-a-service (BaaS) platform that exposes a full set of REST APIs for data persistence, user management, file storage, publish-subscribe messaging, push notifications, geolocation, caching, and atomic counters, plus serverless Cloud Code (custom API services and timers). Requests are authenticated with an application id and REST API key carried in the URL path and a user-token header for authenticated sessions.

Backendless publishes 8 APIs on the APIs.io network, including Cache API, CloudCode API, Counters API, and 5 more. Tagged areas include Backend-as-a-Service, Visual Development, Low-Code, Database, and Real-Time.

Backendless’ developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/backendless: open an issue to ask a question, or submit a pull request to add artifacts.
